Poultry breeding has been in a vital position in the domestic agricultural industry, but with the frequent occurrence of extreme weather and the invasion of diseases, poultry breeding is often greatly affected. Scientific and professional breeding venues can effectively reduce the disease and the impact of the weather, and enable poultry to grow healthily, but the relevant investment amount of such places is higher. Then let’s introduce the construction method of smaller the simple chicken greenhouse. If it can be standardized, and scientific management can also produce greater benefits.
First of all, pay attention to the selection of the shed site: Chicken -raising greenhouses are best to choose from high and dry places. One thing that needs to be noted here is that it should not be built in the mud, because the mud surface plus the poor breathability of the greenhouse will cause the humidity of the chicken greenhouse, and the humidity is too much taboo for poultry breeding. In addition, there must be good drainage facilities in the construction location, and it should not be too close to the road. It is best to stay away from more than half kilometers. You can choose a tall tree tree, in the forest, or next to the forest land.
Chicken -raising greenhouses can be used in the form of plastic greenhouses. There is no drop film in the top layer of the greenhouse, and it is covered with a layer of 5-10cm thick straw to form a heat insulation layer. A layer of plastic film is covered on the straw, and the rope is used. Fixed strong. Pay special attention to the insulation and firmness of chicken greenhouses.
Secondly, the material of the chicken greenhouse is selected: the skeleton skeleton usually uses the steel structure skeleton, which is similar to the structure of the vegetable greenhouse greenhouse. The height needs to be determined according to the needs of the breeding, because the chicken greenhouse may adopt a three -dimensional breeding method, which saves land. It is also more convenient to manage, so that there will be some requirements for the height of the greenhouse, and a reasonable analysis will be determined.
The most widely used in greenhouse sealing materials is plastic membranes. The most widely used in winter insulation is straw ravioli, as well as reinforced plastic membrane and grasshoppers, as well as load columns, wood or bamboo in the greenhouse.
It should not be too large, the number is best to control at 6-7/㎡, and the total amount in each greenhouse should not be too large. It needs to be strictly controlled. Essence
The ground is best to lay brick structures or layers of fine sand. In short, no matter which method is adopted, it must ensure that it is dry in the greenhouse. If the size of the chicken greenhouse is large and there are more poultry, it is easy to produce air inactivation, so ventilation facilities need to be installed to promote ventilation in the greenhouse.
Construction method of breeding of meat chicken breeding greenhouses（Replenish）
Selection of the shed site: It is best to choose a place where the ground is open, ventilated, close to the water source, no pollution of the soil, and no noise on the avenue of the avenue. Anyone who meets the above requirements, such as fields, village open spaces, orchard vegetables, river beaches, etc. can be used. This can provide a suitable living environment for meat chickens.
Architectural specifications: The current one is double -diagonal large shed with a length of 2-30m in length and 7-8m wide. It is moving or north -south. The construction area is 140-240 square meters, and 1000-1500 meat chickens can be raised. Calculated according to 30m in length of the shed, 200 bamboo poles of about 4.5m in length, 20 bamboo poles with a length of about 8m, and about 2500 bricks. In addition, the appropriate amount of fine rope, wire, wheat straw or grass -gardenia must be prepared.
① The brick wall at both ends of the greenhouse, the door in the middle of the gables at one end, wind holes on both sides, and the gables on the other end only leave the pores or install windows, and 1-2 tobacco stoves can be used for pads or heating. Essence Between the two brick walls, every 2M -column, one in the middle (the same height as the top of the shed), 2 on each side of the left and right sides (2 of which are the same as the outside of the shed). There are 5 rows of columns. Each -the top of the pillars is connected to the top of the pillar to form a vertical bracket of the greenhouse. Then use a 45m bamboo pole -group. Tied to the section, 30-40 cm per interval between the horizontal direction, and the enclosure is tied to the vertical column, forming a horizontal bracket on the top of the greenhouse. In this way, a complete greenhouse bracket is completed.
② Plastic film sticks in advance according to the length and width specifications. When covering the membrane, select without wind and rain, and put the membrane directly on the scaffold. Then cover the L0-20 cm thick wheat straw or other weeds on the plastic film (to prevent the grass from decline, you can cover it with a plastic net). Adding a layer of grass or oil on it, adding iron and buried land anchor to fix it. The top of the shed is set up every 3-4m of the exhaust holes with a diameter of 40-50 cm. The drainage ditch is dug around the shed to drain the water in the rainy season.
Preparation before the use of broiler breeding greenhouses
Thoroughly clean up the equipment and dust in the chicken house, and the earth can be exchanged for new soil to the surface of the earth. Check and repair the heating light and other equipment in the chicken house to eliminate the hidden fire hazards. Prepare fuel, electric light guns, light mouth, etc. Drinking water feeding appliances should be soaked and disinfected with 2 % fire alkali liquid for more than 12 hours, then rinsed with water, and cool and dry.
After the chicken shed ground is dry, a 2.5 % fire alkali liquid is sterilized on the inside of the shed. Put the clean and dry pads that are not less than 5 cm in the dry ground, such as short straw, wheat straw (6-10 cm), rice bran, peanut shell, etc. in the later period. Low all the drinking water and feeding appliances evenly.
After sealing the chicken sheds, the sheds and potassium permanganate fumigated for 48h. After disinfection, open the shed film, door, and ventilation holes to ventilate ventilation. Method: The new chicken house uses Forma 28m1, potassium permanganate 14g, and 14ml of water per meter. The old chicken houses that have raised chickens are folderlin 40m1, potassium permanganate 20g, and 20ml of water. First dissolve potassium permanganate into the porcelain basin of the water, and then pour Forma Lyl. The pads should be cleaned around the porcelain pot. Be careful not to use a plastic basin, otherwise it is easy to cause fire.
Before entering the chicks, there must be a preheating process of more than 24h or more, so that the temperature in the cure sheds is kept at 32-35 ° C. In addition, it should be prepared enough warm water.
Breast chicken breeding greenhouse environment control
The kernels have strict temperature requirements throughout the feeding period. There are experiments that the appropriate temperature is 1 ° C after 5 weeks of age, and the body weight of each meat chicken is reduced by about 20g at 8 weeks. The range of the suitable temperature of meat and chickens is as follows: 1-2 days old 34-35 ° C, 3-7 days old 32-34 ° C, 8-14 days old 30-32 ° C, 15-21 days old 27-30 ° C, 22- 22- 28 days of age 24-27 ° C, 29-35 days of age 21-24 ° C, 35 -day age to the out of the column at about 21 ° C. It should be noted that the temperature listed above refers to the temperature at the height of the chicken back. Whether the temperature is appropriate, in addition to observing the thermometer, you can also judge through the activities of the chicken group. When the temperature is normal, the meat chickens are lively, distributed uniform, good appetite, appropriate drinking water, do not squeeze when sleeping, quiet, no screams. When the temperature is too high, the chickens are not easy to move, stay away from the heat source, breathe open, reduce the amount of food, decreases the amount of drinking water, often occurs diluted. Long -term deviations grow slowly, and feathers lack gloss. When the temperature is too low, the meat chicken actively approaches the thermal source, emits continuous screams, is not quiet during night sleep, and it is easy to squeeze and even cause pressure or stray death.
The relative humidity range of meat chicken is 5O % to 70 %. Generally, the temperature is larger before the age of 10, which can reach 70 %, which is beneficial to the absorption of the internal yolk of the chick’s belly and preventing the chicks from dehydration. The relative humidity is less after the age of 10, which can be maintained at about 65 %, which is conducive to keeping dry in the shed and preventing the coccidii disease from causing the cushion.
